Radiotherapy is one of the main treatments for tumors. Currently, about 80% of tumor patients need to receive radiotherapy at different stages of the disease process. According to the World Health Organization, 55% of malignant tumors can be cured, of which 49% are cured by surgery, 40% are cured by radiotherapy, and 11% are cured by drugs and other methods, which is enough to see the status of radiotherapy in the treatment of tumors. Like surgery, radiotherapy is a local treatment. Radiation therapy uses advanced treatment equipment and technology to accurately deliver a high radiation dose to the tumor to kill the tumor cells while the dose to the surrounding normal tissues is very small, thus eradicating the tumor with minimal damage to normal tissues. This ensures both the survival and the quality of patients’ survival. In recent years, with the rapid development of precise radiotherapy technology with precise positioning, precise planning and precise treatment as the core, the overall efficacy of radiotherapy has been improved. Our hospital has invested heavily in a complete set of linear gas pedal radiotherapy system produced in the United States, which is the most advanced radiotherapy equipment in the world today and is the best equipment to carry out precise radiotherapy technology represented by stereo conformal intensity modulated radiotherapy with excellent performance and reliable effect. The perfect combination of technology and equipment is the key to cure tumor. The Department of Radiotherapy of Weifang People’s Hospital has been established since the 1960s, and through the unremitting efforts of several generations, it has become the leader in the province and the top level in the city in terms of technical level, equipment level and treatment concept.
